and more compact plant. C. adpressa of this group is one of the hand- 
somest of the Cotoneasters for the rock garden or for the edges of beds 
of taller shrubs. 
2. Large shrubs with white flowers and red or orange-red fruits. 
In this group are Cotoneaster multijiora calocarpa, C. racemijlora and 
its variety soongorica, C. gracilis and C. hvpehensis. These are per- 
haps the handsomest Cotoneasters which can be grown in this climate. 
The first is the earliest of the Cotoneasters to bloom, and its flowers 
in compact clusters have covered for more than two weeks now its grace- 
fully arching branches on which the blue-green leaves are fast expand- 
ing. The orange-red fruit arranged in compact clusters ripens in Sep- 
tember. Of the two forms of C. racemijlora the var. soongorica is the 
handsomer and perhaps the handsomest of the Arboretum Cotoneasters, 
and one of the handsomest shrubs of recent introduction. In habit and 
in the color of the leaves it resembles C. multijiora calocarpa, but the 
flowers are larger and the fruit is more brilliantly colored. C. hupe- 
hensis is a tall, broad, fast-growing shrub with dark green leaves, with 
larger flowers than those of the other species arranged in many-flow- 
ered compact clusters which cover the branches. The fruit is scarlet 
and lustrous, but in the Arboretum is only sparingly produced and is 
covered by the leaves. Seen from a distance when in flower this Coton- 
easter looks- like a large well-flowered Spiraea. 
3. In this group may be placed the species with red flowers and red 
fruit, C. bullata, C. bullata var. macrophylla. and war. Jloriburida, C. 
Dielsiana and its variety elegans, C. Zabellii and its variety miniata, 
C. Franchetti and C. obscura. C. divaricata and C. Dielsiana are per- 
haps the best garden plants in this group. They are large shrubs with 
wide-spreading, slightly drooping branches, small dark green lustrous 
leaves, and small inconspicuous flowers and fruit. C. Franchetti has 
not proved perfectly hardy in the Arboretum. 
4. In this group are placed the species with red flowers and fruits 
such as C. nitens, C. acutifolia and its variety villosula, C. ambigua, 
C. foveolata and C. moupinensis. C. nitens, though its flowers and 
fruits are small, is perhaps the handsomest of the group for none of the 
Chinese Cotoneasters have more gracefully spreading branches and more 
lustrous leaves. By some persons it is considered one of four or five of 
the handsomest of the Chinese Cotoneasters which can be successfully 
grown in this climate. C. moupinensis and C. foveolata are the tallest 
of the Chinese Cotoneasters with larger leaves than the others. They 
are coarse and not very attractive shrubs, but the brilliant colors of 
the leaves of C. foveolata in autumn make it worth growing in large 
shrubberies. 
Several species of Cotoneaster which do not come from China are 
established in the Arboretum. The best of these for this climate are 
perhaps the red-fruited European C. tomentosa, C. integerrima, a 
black-fruited Siberian shrub and one of the handsomest species, and 
the Himalayan red-fruited C. macrophylla with stems only a few 
inches high and gray-green leaves. The last and the Chinese C. ad- 
pressa are the best of the hardy species for the rock garden for which 
they are well suited.
